I searched the forums but couldnt find the answer.
I just purchased an Equinox and I want to replace the factory radio and need to know how risky that is or what functions I may loose. (I will get this professionally done of course) Crutchfield.com makes it sound like I will loose some 'check engine' tone that can be sent to factory radio, but I dont know how important that is and is there another way to indicate. Is it not as common these days for people to swap out radios? I think the quality is still lacking and I want something with external input so I can hook up my iPOD easily.
